Dear Stata users ,
I am using this command to run a OLS regression:
forvalues i=1977/2007 {
reg dependent_var indep_var1 indep_var2 if Observation_Year <= `i', robust cluster (firms)
}
However, STATA displays in this case "no observations" and it is not possible to run the regression.
For instance, in 1980, I have observations of the second independent variable and the dependent variable only, but I thought that STATA would ignore this year and continue the regression in 1981 instead. Obviously, it is not the case!
So what should I do about this problem ? Any ideas???
Thank you very much !
Bastian S
